Prosecutor, Pam Smith, said the couple went to a 21st at Fleetwood’s Working Men’s Club on May 13, and Johnson accused his four-weeks pregnant partner of staring at another man,

Once home they argued and he grabbed her by the wrists and dragged her to a sofa which he pushed her onto.

The row continued and when she tried to phone police he grabbed her phone and smashed it. Johnson then pinned her to a door by her neck. She said she struggled to breathe and said: “Get off me, I’m pregnant.”

The victim said she was forced to bite Johnson to get him off her. In a victim’s impact statement she said: “I can’t believe it. I’m in total shock. I can’t have a child with someone like that.”

When interviewed Johnson told police his partner had drawn a knife on him. He said he had been fed-up that night because she had been drinking and was pregnant with their first child.

Suzanne Mugford, defending, said her client accepted pushing his girlfriend but denied grabbing her by the throat.

Johnson was bailed for a hearing where both prosecution and defence evidence will be heard.
